Note.— It may assist controllers to know that the above information should be passed in the following order:

1)Fix

2)Level

3)Inbound track

4)Right or left turns

5)Time of leg (if necessary)

7.4VFR ARRIVALS

Depending on the procedures in use, the pilot of an arriving VFR flight may be required to establish contact with the approach control unit and request instructions before entering its area of jurisdiction. Where there is an ATIS broadcast, the pilot should acknowledge if it has been received; where no ATIS broadcast is provided, the approach controller will pass the aerodrome data.

7.5VECTORS TO FINAL APPROACH

7.5.1Vectors are given to arriving flights to position them onto a pilot-interpreted final approach aid, or to a point from which a radar-assisted approach can be made, or to a point from which a visual approach can be made. In the following example, an identified aircraft inbound to Georgetown is given radar vectors to the ILS.

Note.— The radar controller should advise the aircraft of its position at least once prior to turning onto final approach.

7.5.2 In the example above, the approach speed of the aircraft is reduced in order to ensure adequate separation from the preceding aircraft. Speed adjustment can often reduce the need for radar vectoring in establishing an approach sequence. Where speed adjustment would be insufficient to ensure correct spacing, it may be necessary to issue additional vectors.

7.6SURVEILLANCE RADAR APPROACH

On a surveillance radar approach (SRA), the pilot is given distances from touchdown, advisory altitude or height information and azimuth instructions so as to be able to carry out an approach. In the following example, it is presupposed that the aircraft has been vectored to intercept the final approach track at 8 NM from touchdown at 2 200 ft QNH and that the touchdown elevation is 300 ft. Advisory altitudes relate to a 3 degree glide path.

Note 1.— Where an SRA procedure terminates at 2 miles from touchdown, the distance from touchdown and advisory altitude checks are normally passed at 1 mile intervals. Where the SRA terminates at less than 2 miles from touchdown, such checks are given each half mile.

Note 2.— Aircraft replies are expected to all transmissions. However, when the SRA terminates at less than 2 miles from touchdown, the controller’s transmissions should not be interrupted for intervals of more than 5 seconds once the aircraft is within 4 miles from touchdown and aircraft replies are then not expected.

Note 3.— When the pilot reports runway in sight during an SRA and there is reasonable assurance that a landing will be effected, the SRA may be terminated.

Note 4.— An example of pre-computed levels for a 3 degree glide path, where the elevation of the touchdown point is 300 ft AMSL, appears in Figure 2.

7.7PRECISION RADAR APPROACH

7.7.1In a precision radar approach, the controller, in addition to providing heading instructions during the continuous talkdown, provides information on altitudes relative to the glide slope, together with instructions on corrective action in the event that the aircraft is too high or too low. In the following example, based on a 3 degree glide slope to runway 27 at Georgetown, it is presupposed that the aircraft has been radar vectored into precision approach radar (PAR) coverage and has been identified to the PAR controller by radar transfer.

7.7.2 When the radar returns on the elevation element of the PAR indicating that the pilot may be making a missed approach, the radar controller shall, when there is sufficient time to obtain a reply from the pilot, pass the aircraft’s height above the glide path and ask the pilot if a missed approach is intended.

. . . SLIGHTLY ABOVE GLIDE PATH 3 MILES FROM TOUCHDOWN . . . STILL ABOVE GLIDE PATH 2½ MILES FROM TOUCHDOWN — GOING FURTHER ABOVE GLIDE PATH 2 MILES FROM TOUCHDOWN ARE YOU GOING AROUND

7.7.3 In similar circumstances, but when there is not sufficient time to obtain a reply from the pilot, the controller should continue the precision approach emphasizing the aircraft’s displacement. If it becomes apparent that the pilot is making a missed approach, either before or after the normal termination point, the radar controller shall pass missed approach instructions.

AREA CONTROL

8.1AREA CONTROL UNITS

8.1.1Area control units vary in size from simple one-person procedural units to large sophisticated centres which may contain departure, arrival and terminal control sections equipped with radar. RTF phraseology given below would be suitable for any of the above air traffic services.

8.1.2Much of the phraseology used in area control is of a general nature and is detailed in Chapter 3. However, many instructions used in area control (particularly where radar is not available) are related to specific conditions in order to maintain aircraft separation.

8.1.3The following examples provide a cross-section of phraseology used in area control. They may be varied, or added to, by combining their component parts according to the requirements of the prevailing traffic situation.
